Short description
Identification keys | Morphology | Morphometrics
Dorsal spines (total): 10; Dorsal soft rays (total): 43 - 44; Anal spines: 2; Anal soft rays: 40. Color in life unknown. Coloration in preserved specimen a fine peppering of chromatophores on body and a somewhat dark wedge-shaped area of pigments at caudal-fin base. Segmented caudal rays 11; dentary incisors with arrowhead-shaped tips; interorbital pores 4; body very elongate, depth about 12.7 in SL (Ref. 90102).
Body shape (shape guide): eel-like; Cross section: oval.
Based on characters common to the family, this species is oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114). Only record is of 2 specimens collected from 1919 by dynamite from Jolo Island, Philippines (Ref. 90102).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Trophic level (Ref.
69278): 3.6 ±0.7 se; based on size and trophs of closest relatives
Resilience (Ref.
120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
